BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram illustrating a schematic configuration of a preceding vehicle information display apparatus using a head-up display according to an embodiment of the present invention; FIG.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]
FIG. 3 is an exemplary view showing the preceding vehicle information displayed in the specific format set in the head-up display by distinguishing the case where the preceding vehicle is close to the driver's vehicle and the case where the preceding vehicle is far away.

Hereinafter, an embodiment of an apparatus and method for displaying preceding vehicle information using a head-up display according to the present invention will be described with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 1 is a diagram illustrating a schematic configuration of a preceding vehicle information display apparatus using a head-up display according to an embodiment of the present invention.

1, the preceding vehicle information display apparatus using the head-up display according to the present embodiment includes a preceding vehicle detection unit 110, a distance detection unit 120, a control unit 130, and a head-up display 140. [ .

The preceding vehicle detection unit 110 detects a preceding vehicle in front of the vehicle (i.e., a target object).

The preceding vehicle detection unit 110 may detect an obstacle by using a Lada sensor, a radar sensor, a camera, or the like, and may include other types of object detection sensors (e.g., an ultrasonic sensor, an infrared sensor, etc.) You may.

For reference, the LIDAR (Light Detection And Ranging) sensor is a sensor that can be used to measure the position coordinates of a reflector by emitting a laser pulse and measuring the time of reflected and returning.

The distance detecting unit 120 detects a signal reflected from the preceding vehicle in front of the viewing direction (or the vehicle traveling direction) (in a state in which the steering wheel is not rotated and is kept within a specific angle range) The distance between the vehicle and the driver can be detected.

In the present embodiment, the functions of the preceding vehicle detection unit 110 and the distance detection unit 120 are separately described for the sake of convenience. However, according to the embodiment, the preceding vehicle detection unit 110 and the distance detection unit 120 are integrated .

The control unit 130 determines whether the preceding vehicle is a reference vehicle of the smart cruise control function through the head-up display 140 based on the distance to the preceding vehicle ahead in accordance with the information detected through the distance detection unit 120 Display information.

However, when executing Smart Cruise Control function, the driver can set the distance from the preceding vehicle.

For example, the distance between the preceding vehicle and the driver's vehicle can be set to be shorter in a city road section with many vehicles, and the distance between the preceding vehicle and the driver's vehicle can be set to be relatively longer in a section with a smaller vehicle.

However, in the case of driving on a road section in the city, there is a problem that a vehicle intervening between the preceding vehicle and the driver's vehicle frequently occurs. In the case of driving on a long-distance road section, There is a problem in that the distance from the preceding vehicle set for the smart cruise control function becomes long and the preceding vehicle is far away.

In a situation where the above problem occurs, it is necessary for the driver to reliably maintain the smart cruise control function only by knowing which preceding vehicle is operated based on the smart cruise control function.

Of course, the driver can assume that the smart cruise control function is being performed on the basis of the nearest preceding vehicle ahead of his vehicle, but it can be assumed that the road is curved, the preceding vehicle is far away, or the preceding vehicle is traveling , It is necessary to display the predecessor vehicle on which the Smart Cruise Control function is to operate, because it may not be possible to accurately determine whether the smart cruise control function is being performed on the basis of a certain preceding vehicle.

However, when the preceding vehicle is close to the driver's vehicle and the preceding vehicle is far from the driver's vehicle, the visibility (or discernment) of the driver may be reduced if the same type of preceding vehicle is displayed as a reference for the smart cruise control function There is a problem.

Therefore, in the present embodiment, when the preceding vehicle, which is a reference of the smart cruise control function, is located near the driver's vehicle and the preceding vehicle is farther from the driver's vehicle, the driver's visibility (or discrimination power) (See FIG. 3).

FIG. 3 is an exemplary view showing the preceding vehicle information displayed in the specific format set in the head-up display by distinguishing the case where the preceding vehicle is close to the driver's vehicle and the case where the preceding vehicle is far away.

3 (a) and 3 (b), when the preceding vehicle is far from the driver's vehicle, the controller 130 displays the preceding vehicle information in a first format (for example, Icon, an arrow icon, a vehicle icon indicating the reference vehicle of the smart cruise control, and the like).

3 (c), when the preceding vehicle is close to the driver's vehicle, the controller 130 displays the preceding vehicle information in a second format (e.g., an icon of a shape surrounding the vehicle, An icon surrounding the four wheels of the vehicle, etc.).

At this time, the preceding vehicle information of the first type displayed on the upper portion of the preceding vehicle and the preceding vehicle information of the second type displayed on the lower portion of the preceding vehicle are not necessarily different, and the same type may be used if the visibility is good. The preceding vehicle information may be applied to specific colors or special effects (e.g., flicker, fluorescence, concentric wave, animation, etc.).

The head-up display 140 displays the preceding vehicle information (for example, marker information of a specific format displayed at the top or bottom of the preceding vehicle using icons) under the control of the controller 130 (I.e., an augmented reality image).

FIG. 2 is a flowchart illustrating a preceding vehicle information display method using a head-up display according to an embodiment of the present invention.

As shown in FIG. 2, the controller 130 determines whether the current vehicle is performing a smart cruise control function (S101).

If the current vehicle is performing the smart cruise control function, the control unit 130 detects the preceding vehicle as a reference of the smart cruise control function (S102).

The preceding vehicle, which is a reference of the smart cruise control function, is information that can be known through the preceding vehicle detection unit 110.

That is, based on the position and distance to the preceding vehicle detected using a sensor (not shown) such as a Lidar sensor, a radar sensor, or a camera of the preceding vehicle detection unit 110, will be.

The control unit 130 detects the distance from the driver's vehicle to the preceding vehicle through the preceding vehicle detection unit 110 (S103).

Or you can use the Smart Cruise Control function to know the distance from the driver's vehicle to the preceding vehicle.

When the distance from the driver's vehicle to the preceding vehicle is detected as described above, the controller 130 determines whether the distance from the driver's vehicle to the preceding vehicle is equal to or greater than a preset reference (S104).

If the distance from the driver's vehicle to the preceding vehicle is equal to or greater than a predetermined reference in accordance with the determination (S104), the controller 130 displays the head-up display 140 in the first format using the preceding vehicle information Specific marking information displayed on the top or bottom of the preceding vehicle) is generated and displayed as a virtual image (S105).

If the distance from the driver's vehicle to the preceding vehicle is not equal to or greater than the predetermined reference value in step S104, the controller 130 controls the head-up display 140 to display the preceding vehicle information in the second format (E.g., marking information of a specific format displayed on the upper or lower portion of the preceding vehicle) using the virtual image as a virtual image (S106).

For reference, the preceding vehicle information of the first type displayed on the upper portion of the preceding vehicle and the preceding vehicle information of the second type displayed on the lower portion of the preceding vehicle are not necessarily different, and the same type may be used if the visibility is good . The preceding vehicle information may be applied to specific colors or special effects (e.g., flicker, fluorescence, concentric wave, animation, etc.).

As described above, the present embodiment displays a stable augmented reality image on the head-up display 140 when the smart cruise control function is performed, thereby improving the reliability of the smart cruise control function and assisting the driver in safe driving .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, I will understand the point. Accordingly, the technical scope of the present invention should be defined by the following claims.
